SHIELD 0R PROTECTOR RADIATORS.

Application led March 6, 1915.

To all whom t may concern:

Be it known that I, VVAi/rnn C. FARRELL, .a citizen of the UnitedStates, residing at Buffalo, in the county 'of Erie and State of NewYorln'liave invented a new and/.useful Improvement in Shields orProtectors for Radiators,l of which the following is a specification.

This invention relates to shields or proteotors for Such protectors areused for thel radiators of water cooled automobile engines during coldweather for the purpose of preventing thc water in the radiator fromfreezing when the engine is not running. and for regulating theadmission of air to the radiator so as not to chill the water enough todeleteriously affect the operation of the engine.

Theobject of the invention is to rovide a practical and desirable deviceof this character of strong and simple construction, which can bereadily attached `to the radiator of an ordinary automobile and which'can be so operated, from the drivers seat of the machine if desired` asto cut on?, either partially or entirely, the supply of air admitted tothe radiator.

In the accompanying drawings:

Figure 1 is a front elevation of an automobile radiator of standard typehaving fitted thereon a protector embodying the invention, the protectorbeing opened so as to admit air to the radiator.

Figa .2 is a similar view, showing the vprotector entirely closed.

Fig. 3 is a rear sectional elevation of the protector,u on an enlargedscale', showing the radiator by dotted lines.

tector closed.A

Fig. 4 is a section on line 1 -4, Fig. 3, looking in the direction ofthe arrow.

Fig.I 5 is a similar View, showing the pro- Fig. Gis a sectional .planview of the protector attached tO the radiatOI.

The protector or shield is made of sheet metal or of any other suitablematerial and consists primarily of anl outer or stationary and an inneror movable plate or section,

air i11- let ports which are adapted to register when it is desired toadmit air tothe radiator,

andwhioh can be moved, wholly or partially, out of' alinement in orderto limit or shut oil' .the air to the radiator. The outer or xed sectionis attached to the front of the Specication of Letters Patent.

radiator by suitable means7 and the inner section is adapted to be movedin guides on the 4outer section so as to increase or decrease the supplyof air admitted to the radiator, aS hereinafter described.

9 represents the outer fixed section of' the protector which, as shownin the drawings, is substantially square in outline' but which can ofcourse be made of suitable shape to fit the fronts'of radiators ofdifferent makes.

This section 9 consists of a substantially flat front plate 10 and'marginal flanges or members 11' which extend at right angles thereto andwhich at the sides of the protector have flanges 12 extending inwardlyfrom the edges thereof. Angle strips 13 are secured in any suitablemanner to the side members 11 parallel to the front plate and form onewall of the slots or guides 14,' the other wall thereof being formed bythe parallel vertically arranged strips 15 which are adjacent to thefront plate 10.

IPhe movable section or plate 16,'Whic'h is approximately the same shapebut slightly smaller in size than the( 'uter vsection,'has side edgeportions 17 which extend into and are adapted tovbe guided by the slots14, So

Vthat the section 16 is capable of vertical the weight of the sectionand `make it slide more freely in the guide slots. Because of thespacing strips'l the two sections, while close together, are not inactual Contact and therefore oannotbecome stuck or jammed.

The movable section is provided. atth'e top thereof with an inwardlyextending "cross piecerange 19. g*

While the construction described'I is' the preferable'one, yet anymethod -of slidably mounting the movable section on the liXed sectionwhich allows the movable section to slide freely in a plane parallelwith the plane of the fixed section can be used in place thereof. v

20 represents a number of small openings or ports., formed in theVouteror'ixed section, which are preferably square-in outline,

`and 21 is a number. of similar openings formed in the inner or movablesection 16.

end to' the bottoml flange of the xed section and at itsupper end to thetop flange or `A spring' 22', preferably attached at 'its lower crosspiece 19 of the movable member, serves .to normally keep the innersection in the lowered position, shown in Figs. 1 andB, so that theports or openings 21 thereof register with the openings of the outersection and the outside air is free to enterv the radiator.

Means of various different sortsl could be employed for shifting themovable section so as tocut off theair to the radiator as desired, thefollowing means being shown for the purpose:

A rocking crank or lever 23 is bolted or fastened in some other suitablemanner to the front of the radiator above the protector, and a rod orchain 25 connects one end of this lever With the center of the top piece19 of the'movable section of the radiator. The other end of the leverhas a Wire or cord 26 fastened-thereto, which 'Wire passes downwardly infront of theprotector and over a pulley 27 which is mounted at thebottom of the radiator. From there it leads to the driversseat so thatby means thereof the driver can raise the inner section'relatively tothe outer section into suoli position as to limit or cut olf the supplyof air ad l mitted to the radiator asdesired. The Wire front ofthe'radiator in any suitable man'V ner. As shown, the flanges 12 abutagainst the' radiator front,fitting Within a marglnal' bead 28 on theradiator, While bolts 29 pass through the two sections and the airpasoperation of the engine in cold Weather. Allv this can beaccomplished from the drivers seat Without trouble and no furtherattention need be paid to the protector until it is again desired tovary the amount of air ad-l mitted.

I claim as my invention:

`The combination of a protector comprising an integral outer sectionContaining a number of' openings therein, means for se curing the outersection in front of an automobile radiator, an integral inner sectionadapted to move vertically parallel with the plane of said outer sectionand also containing a number of openings adapted to register withopenings in the outer section, operating means controlled from thedrivers seat for moving the inner section in a Vertical plane andrelatively to the xed section', and spring means connecting the fixedand movable sections for returning thev movable section to normalposition.
